The Effective Use of Dynamic Testing in Raw Materials Development Programs

Dynamic test equipment is used to characterize elastomers and compounding ingredients for the purpose of selecting those most suitable for the various types of dynamic mountings and to develop formulations with balanced properties. Key measurements include modulus under conditions of dynamic vibration, damping, and the ratios by which these quantities change with changes in frequency, amplitude, and temperature. By appropriate selection of test specimen configuration and test conditions, additional data are generated which can guide the designer in the most effective use of the materials available and help define the relationships between the properties of mount materials and their effectiveness in controlling vibrations in vehicles.
